Pupe and her place are great! The location is wonderful and the apartment is very lovely. We stayed at her's for two nights at the beginning of our Thailand-trip and it was perfect. We should have booked more days at her apartment. The area around the place is not too noisy at night and local transport is only some minutes away.
For backpackers: the train station is just 5-10 minutes away by foot and Chinatown is also a wonderful place in Bangkok!
